As was speculated earlier this week, the IEEE Task Group (TG3a) charged with the task of determining and ratifying a single ultra wideband standard has voted to disband. Obviously, the fight between the WiMedia Alliance and the UWB Forum and their competing specs has been deemed unresolvable, so the IEEE has decided to cut bait.
As a result, the companies that comprise the members of both groups will be pretty much left to their own devices to build products that fit their faction's UWB spec. What that will mean is that we'll be seeing a bunch of products hit the marketplace that are incompatible and consumers will have to be very careful to make sure what they're buying is right for their needs. What it also means is that the IEEE pretty much threw in the towel without a fight and were pushed around by both groups without showing any mettle to get things resolved.
